Visualisation Tech Ique for Robotic Component Connection Systems

As the construction process moves towards an increasingly automated scenario, the design of fixing systems which can be easily handed by robotic devices becomes an essential factor in the eventual viability of the whole system. This project has studied many common and many uncommon fixing methods, in a survey covering all areas of engineering industry. Some of the methods are already in use in factory automation systems; however, for use with robotic and automation equipment on construction sites a more detailed and innovative approach to assessing the suitability of connectors is required. The paper reports on the use of a mechanical modelling software package which has been integrated into a visualisation system to provide a realistic simulation of the engineering performance of the connector under simulated site conditions. The software permits application of quantified forces and restraints to the mechanical model. This technique has been used as a preliminary stage in the design and assessment of connectors for robotic assembly, and has thereby avoided the necessity of prototype testing numerous different design possibilities. As a demonstration of the method, examples of various feasible connector types for exterior wall cladding with robotic assembly tools are given, these being a rationalised set of fixing systems to satisfy a wide range of sizes, material types, and anchor provisions. It is suggested that this addition to the scope of prefabricated components will generally improve the safety of assembly, assurance of attachment, and provide labour and financial savings to the cladding industry.
